Canon latest patent shows that they are working on a Lens Driving Adapter possibly for EF and EF-S Lenses. It will going to attach on the side of the lens to do the zoom operation by rotating the lens barrel.
Before we begin let me tell you that the Canon PZ-E1 zoom adapter was announced sometime in Feb 18 2016 and that works only with Canon 18-135mm IS USM (Nano) Lens. But this patent was filed on June of 2016 and it was first published on Jan 5, 2017. Hence Canon may be working on improved and versatile version of its current PZ-E1 zoom adapter .
Patent Details (Translated)
The lens driving adapter is detachably attachable to a lens barrel on which an operation member is provided. The adapter includes a driver configured to drive the operation member, and an adapter body holding the driver. The adapter body includes a first contact portion and a second contact portion that are protrusions contactable with two circumferential portions in an outer circumferential surface of the lens barrel. The first and the second contact portions are contactable with outer circumferential surfaces of lens barrels whose outer diameters are mutually different. The adapter body includes a fixing member configured to fix the adapter body to any of the lens barrels.

If you are a owner of a 50mm F1.8 Lens or the standard kit lens then you can use them as reverse macro lens and it’s also the least expensive way to get Macro shots from your camera. The technique involves reversing of your lens and attaching to your camera mount either with the help of steady hand or external adapters are also there to attach a reversed lens.
Canon is also taking reverse lens technique serious and finally the are planning to build a multipurpose lens with two lens mount.

Canon working on completely new technology of sensors, the sensor can electronically bend itself to behave like a curve sensor.
Take a look at the translated text – Canon is in a patent for electrically bending the bending sensor. Perhaps even lenses with curvature of field curvature can be supported.
Patent Details
Patent Publication No. 2016-201425
Release date 2016.12.1
Application date 2015.4.8
Canon patent
Coupling the imaging element and the expansion / contraction section
As the stretchable portion expands, the amount of curvature of the imaging surface increases
The expansion and contraction section is electrically controlled
As the stretchable portion of the sensor expands, the amount of curvature of the imaging surface increases.

This is the third time we are publishing a Canon curved sensor patent. Adding a curved sensor in DSLRs and Mirrorless in Canon camera will sure solve the prolonged problem of dynamic range in Canon cameras.
As we all know that Curve sensor mimic the shape of the human eye and collect more light in corner compared to a square sensor resulting massive increase in dynamic range of the camera. Not only better dynamic range due to better absorption of light in the sensor the low-light performance of the camera will also up-scaled to a new level.

Patent Publication No. 2016-197663
Published 2016.11.24
Filing date 2015.4.3
Canon patent
The central portion of the light falloff is not noticeable to the flat shape
The periphery light falloff is noticeable a curved shape
Machine translated text
Canon of the patent application is curved sensor and the suppression of the thickness of the, is the suppression of the deterioration of the shutter efficiency of the focal plane shutter. Bending sensor in the focal plane shutter and the image pickup device since the distance of the center is long and becomes a shutter efficiency decreases, in the patent applications the image pickup device by a curved only the peripheral portion of, while suppressing lowering of the shutter efficiency, curved sensor It seems to obtain the benefits that can suppress the limb darkening of.
The plane sensor curved sensor person if it is replaced with a great camera is thought to be completed also will not a few. However, the shutter of the problem seems to be, curved sensor is the completion of the I do not yet may be ahead of the story.

Canon EF 400mm F2.8 L IS USM with internal 1.4X and 1.7X extender
Latest patent surfaced over the web from Canon shows us a 400mm L series lens with Built-in 1.4X and 1.7X extender. The lens extender is actually a two stage lens extender.
So after implementing the built-in lens extender the 400mm lens will become a 560mm lens and 680mm lens respectively.
Patent Publication No. 2016-191761 (Google Translated)
Published 2016.11.10
Filing date 2015.3.31
Focal length 392.57
F-number 2.90
Angle of view 3.15
Image height 21.64
Overall length of the lens 371.15
BF 44.00
The first state magnification 1.40
The second state magnification 1.70
The lens technology is not new Canon already using the built-in lens extender technology in Canon EF 200-400mm f/4L IS USM Lens tjat features built-in 1.4X lens extender and after hence the 200-400mm we get the focal range of 280-560mm.
The arrival date of lens is not know yet and in general a patent takes upto 2 years to arrive as a real product.
